  23 ; command line options, with each record separated by a blank line,
  24 ; and each field appearing on its own line.  The first field is the
  25 ; command-line switch with the leading "-" removed.  All options
  26 ; beginning with "f" or "W" are implicitly assumed to take a "no-"
  27 ; form; this form should not be listed.  If you do not want this
  28 ; negative form and you want it to be automatically rejected, add
  29 ; RejectNegative to the second field.
  30
  31 ; The second field is a space-separated list of which parts of the
  32 ; compiler recognize the switch.  Current valid entries are "C",
  33 ; "ObjC", "C++" and "ObjC++".  If the switch takes an argument, then
  34 ; you should also specify "Joined" and/or "Separate" to indicate where
  35 ; the argument can appear.
  36
  37 ; Comments can appear on their own line anwhere in the file, preceded
  38 ; by a semicolon.  Whitespace is permitted before the semicolon.
  39
  40 ; For each switch XXX below, an enumeration constant is created by the
  41 ; script opts.sh spelt OPT_XXX, but with all non-alphanumeric
  42 ; characters replaced with an underscore.
